Summer must be drawing to an early close -- or at least the fall is starting early. Buzz is jumping for the Toronto International Film Festival, which runs Sept. 8-18; all eyes are on fourth quarter releases; and one studio is beginning to plan for Oscar, 2012. To help things along, we'll even give you a peek at some trailers for upcoming films -- after the jump.

Two films that are being screened at TIFF released teaser trailers Wednesday -- and both are frightening in their own way. One is Nick Broomfield's not-so-flattering portrait of Sarah Palin in the documentary 'Sarah Palin -- You Betcha.' The clip here has Broomfield himself rudely interrupting a Palin rally -- right after Palin comments about the death panels that were supposed to be part of President Obama's health care program (Palin helped spread the lie about the panels, which supposedly would decide whether some seniors should live or die).

Next is a sizzle teaser for the Canadian post-apocalyptic thriller 'The Day,' which stars Dominic Monaghan, Shannyn Sossamon, Ashley Bell and Shawn Ashmore and is directed by Douglas Aarniokoski. The plot: "In a post-apocalyptic future, an open war against humanity rages. Five survivors wander along rural back-roads, lost, starving and on the run. With dwindling food stocks and ammunition, an attempt at seeking shelter turns into a battleground where they must fight or die."

Two fall films have also dropped new trailers on Wednesday. One is the exciting futuristic thriller 'In Time,' written and directed by Andrew Niccol and starring Olivia Wilde, Amanda Seyfried, Alex Pettyfer and Justin Timberlake, about a world where time has become the ultimate currency: "You stop aging at 25, but there's a catch: you're genetically-engineered to live only one more year, unless you can buy your way out of it. The rich "earn" decades at a time (remaining at age 25), becoming essentially immortal, while the rest beg, borrow or steal enough hours to make it through the day."

Next up is 'Moneyball,' starring Brad Pitt, Jonah Hill, Philip Seymour Hoffman and Robin Wright in the fascinating story of Oakland A's general manager Billy Beane's successful attempt to put together a baseball club on a budget by employing computer-generated analysis to draft his players, turning the 2002 team into a winning proposition.

And, just to let you know that Oscar season isn't too far away, Warner Bros. on Wednesday announced release dates for two high-profile films: The Clint Eastwood-directed Leonardo DiCaprio-starrer 'J Edgar,' about you-know-who, which opens Nov. 9; and the Stephen Daldry-directed drama 'Extremely Loud & Incredibly Close,' about a nine-year-old amateur inventor, jewelry designer, astrophysicist, tambourine player and pacifist, who searches New York for the lock that matches a mysterious key left by his father when he was killed in the September 11 attacks. The Tom Hanks-Sandra Bullock starrer opens Dec. 25 for Oscar consideration, then goes wide Jan. 20. Unfortunately: No trailers for these two. But stay tuned.
